[JamieCounter]

hello everyone new to forum , I'm having an issue with my outboard i started the motor the other day and it started right up so it let it idle for a few min. water pump was working good ! . so i wanted to idle it up a little so for what ever reason i pushed the button as to not put in gear and pushed the lever backward as in reverse the engine started miss firing , so i turned engine off put it back in neutral and tried to restart engine with out success it cranks wont start i have spark when cranking engine i have 80 psi on air side and 85 psi on fuel side and i have also put in new plugs i checked fuel pressure at high pressure pump and it makes well over 100 psi not boat was siiting for probably six months thanks for any help

it cranks wont start i have spark when cranking engine

How much spark? Each measured with an open air device?

Think I would check for continuity on each plug wire, end to end -- also might pull the flywheel and check for loose or damaged magnets.
